Im lookin to replace my exhaust system because it leaks in 3 different places and my cat is completely dead and rattles at stop lights. I live in IL so i need emissions legal but dont want AIR tubes if possible. I already can get 3in exhaust piping, my question is what headers will go best with a L03/3in exhaust setup. I will be swap out the little 305 for a 350 when i get the money so i dont want something just for the 305 i want something that will work just as good with the 350. any help is appreciated.

Same answer.

"Smog legal" and "A.I.R. tubes" go together. What you're saying is like asking for a BLT but hold the bacon.

Of course, if you just want shorties, O2 sensor and y-pipe, you can have that. Hedman and SLP have such. But, that may not get you the "best" setup.
